Oh, seriously f*ck off.
1. You betrayed Iran 4 times at the UN Security Council which brought our economy on the verge of collapse and forced us to accept the JCPOA.
2. You abandoned Tehran-Shomal highway due to US sanctions.
3. You abandoned the Chabahar Port due to US sanctions. Chabahar was offered to you first, not the Indians.
4. You abandoned IR-40 nuclear reactor after Trump pulled out of the JCPOA.
5. You abandoned South Pars gas field in fear of US sanctions.
6. You closed the bank accounts of Iranian students studying in China after the US imposed unilateral sanctions.
7. You abandoned Tehran Metro, again due to US sanctions
8. You did nothing to restore our trade after the US kicked our banks out of the SWIFT.
The Chinese have been tried thoroughly. You are the most useless country on the face of the Earth. Passive, two-faced, submissive to the US to the core (you just signed an agreement with Trump that is 100% against your national interests) and cheap.
The only thing the Chinese culture can export is cheap goods. Period. You can't even export your culture unlike Japan and South Korea. Your only ally in your mind is a tin-pot dictator with a bad haircut that looks like a fat high-school bully.
The best possible outcome of this war is that if the IR falls, we will never see you in Iran again. Not only that, there will not be a drop of oil sold to you without the US permission. And guess what? You're the next on the list. So, enjoy while you can.
